Embodiment Construction

[0022] The following tests were carried out in 3 different areas; there was no significant difference in various factors such as fertilization, irrigation, and management methods not mentioned in the following tests.

[0023] Take pure summer corn and pure summer peanut as the control; pure corn: row spacing 60 cm, corn plant spacing 27.8 cm, plant number 4,000 per mu; pure peanut: 2 rows per ridge, ridge width 85 cm, double-grain hole distance 14 cm , 11,000 holes / mu, or, 3 rows per ridge, ridge width 110 cm, double-grain hole distance 16 cm, 11,000 holes / mu. The corn is 35 cm away from the peanut ridge.

[0024] 8 intercropping patterns: 2 rows of corn (row spacing 55 cm) interplant 2 rows of peanuts, 3 rows of peanuts or 4 rows of peanuts, 3 rows of corn (row spacing 55 cm) interplant 2 rows of peanuts, 3 rows of peanuts or 4 rows of peanuts, 4 Rows of corn (row spacing 55 cm) were intercropped with 3 rows of peanuts or 4 rows of peanuts. Among the 8 intercropping mod...

Abstract

The invention relates to a summer corn and summer peanut intercropping planting method and belongs to the technical field of crop planting. According to the summer corn and summer peanut intercropping planting method, three lines of corn are intercropped with four lines of peanuts, the corn line width is 55cm, the corn planting distance is 15cm, the peanut line width is 33-35cm, the peanut hill spacing is 14cm, the peanuts are planted in a ridging mode, the ridge width is 85cm, two lines of the peanuts are sown in each ridge, and the distance between the corn lines and the peanut ridges is 35cm. Three lines of the corn and four lines of the peanuts are arranged in an alternating mode, intercropping is carried out in a wide width mode, the corn line width, the corn planting distance, the peanut line width, the peanut hill spacing, and the distance between the corn lines and the peanut ridges are strictly limited, and therefore the total output value is remarkably improved.

Description

Technical field [0001] [0002] The invention relates to a summer corn and summer peanut intercropping planting method, which belongs to the technical field of crop planting. Background technique [0003] "The country is based on the people, and the people depend on food." Food is the foundation of human survival and social progress, and the lifeblood of the economy. As the world's most populous country, China's grain demand accounts for a large proportion of the world's total grain demand, and supply and demand have always been in a tight balance. my country's existing corn planting area is 520 million mu, of which Huanghuaihai is the most important and concentrated summer corn production area in my country. This area has sufficient light and heat resources to meet the growth needs of corn and peanuts, and there is no natural condition restriction. [0004] Intercropping is the essence of traditional Chinese agriculture. A reasonable intercropping model can not only inte...
